Host to System Controller Loopback Test (hsclbtest)
|
hsclbtest verifies the proper functioning of the Host to System Controller interface in Sun high-performance UltraSPARC T1 (Chip-Multithreaded [CMT] Multicore Processor) CPU based entry level servers.
hsclbtest exercises the Host to System controller (SC) interface for making sure that the Host to SC communication path is functional and reliable. The test essentially sends and receives packets from Host to SC on SunVTS virtual channel and verifies the contents of the packets that sent and received for integrity.
hsclbtest Options
